Subject: Skip Bison api.token.raw probe if Bison is not found.
X-Git-Tag: v1.3~66
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/eb7be85350a2dd971bb509e9191c33fc640cd0d5

Skip Bison api.token.raw probe if Bison is not found.

Printing the api.token.raw probe when Bison was not found at all gives
strange configure output, let's just make the whole check conditional.
